Hi Steve,

It would be interesting to track down the reasons for these differences,
and perhaps we can use it to improve the 2.1.xx performance. The first
test I'd like to see is for you to switch the kernels running on the two
boxes and see what part is due to hardware/system differences.

Beyond that, see if you can distill the essence of midnight commander
into a script, and if 2.1.xx is still lagging behind I'll try to speed
it up.
